ABSTRACT:
A control device for a throttle valve is provided, which, by dispensing a position sensor for the throttle valve, can reduce a cost of the sensor and which is excellent in durability and reliability and is reduced in its control delay. The control device includes an air flow sensor1for detecting an air flow rate flowing through an intake pipe of an internal combustion engine, a motor33for driving the throttle valve2disposed in the intake pipe and an ECU15for controlling the driving operation of the motor. The ECU100feedback-controls the output of the air flow sensor so that a difference between the output of the air flow sensor1and an air flow rate required for the engine reduces.
